To 1Z5 wi one it may concern.

Be it known that If, JOgIN VJ. BROWN, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Automobile-Lamps, of which the following is a specification.

This invention relates to lamps and is particularly directed to the improvement of lamps designed for use upon automobiles for holding the lamp body reflector and lens ring in their properly associated relation.

rwi'ure for resiliently holding the lens proper position upon the lamp the same time prevent the reflecmming an improper position. In intended. that the reflector shall al y held against such movements as tend to destroy the focal relation been it and the illuminating lamp.

The novelty as well as the utility of the sent s-ructure will be more apparent in a detail description of the accompanysheet of drawings which represents the rred embodiment of my invention. in see. drawings, similar characters of refer designate corresponding parts and, gore i is a View in cross section of an nobe head light embodying the feaof invention, D s a front or face view of the struc- 0 shown in Fig. l with the lens ring reis a fragmentary section taken on 3 of Fig. 1 and illustrates thermallin which the parts are held in their eociated relation,

' r body itself has been shown of 153i form a d is designated by the nerai 1. This lamp body can iy projecting shelf structure n outer end, the present illustration showing this shelf as being continuous but this continuity is not essential. A reso movement to destroy its focal relation with The main object of my, invention residesthelamp 5. The entire structure is closed by means of a lens ring designated generally by the reference numeral 6 and this lens ring is provided with an innergt'ihu lar flat portion 7 designed to rest' d'uectly upon the reflector flange 4 or upon the sealing core such asshown at 8. This inner annular surface of the lens ring is also provided at suitable intervals with slotted openings 9 through which the engaging portions 10 of the hooks 11 are designed to pass. Likewise, the reflector flange is cut out at proper intervals as shown at 12 to permit the proper application of the reflector. The hooks themselves are formed of a wire shaped as shown particularly in Figs. 3 and 5 and these hooks carry leaf springs 13 at their inner ends which leaf springs engage the under surfaces of the shelf structure 2 as is indicated at 14 to normally draw or urge the hooked ends 11 toward the lamp body.

Thus, when the lamp is constructed, the hooks and leaf springs are mounted in the relation shown so that the shanks of the hooks project through suitable apertures in the shelf structure 2 and the springs 13 carried thereby are in such position to engage the inner under surface of the shelves 2. The reflector is then mounted in a position to pass over the hooked ends 10 and is then given a'slight twist so that the ends of these hooks engage the flange 4. In this manner, the reflector is resiliently held in position and is also prevented from relative movement inwardly or outwardly so as not to destroy the focal relation with regard to the lamp 5. To apply the lens ring, the slotted openings are brought to a position dire tly over the hooked ends 10 so that these e ds may enter the interior of the lens ring and engage the interior of the annular flat portion 7 upon a twist of the ring itself. In this inanner, the parts are held in firmly associated relation by a stretcher which is in itself comparatively simple but possessing a high degree of utility.

What I claim is: l

1. In a headlight, a lamp body, a reflector therein, means carried by said body to limit the inward movement of said reflector, a lens ring, a resilient hook structure carried by said means and free of permanent attachmerit therewith, and means carried by said ging for cooperation with said hook strucare. I i I 2. In ahead light, a lamp body, a reflector I therein, means carried by said body to limit the inward movement or said reflector. a lens ring. and a resilient hook structure for holding said body and ring together, said hook structure being free of permanent attachment with either one.

In a head light, a lamp body, a reflector therein, an inwardly projecting shelf structure arried. by said body, a plurality of hooks loosely passing through said structure, a l af spring secured to each hook intermediate its ends and loosely engaging the un derside of said shelf structure, a lens ring, and means carried by said ring for cooperation with said hooks.

4. In a head light, a lamp body, a reflector therein, a laterally projecting flange on said reflector, means carried by said body on which said reflector rests to prevent its inward movement, a lens ring provided with means adapted to rest on said fit nge, a hook structure for engaging said ring to hold it in engagement with said flange, and spring means located beneath said first named means and within said body but free of permanent attachment with either for pulling said hook toward said body.

5. In a head light, a lamp body, a reflector therein a laterally projecting flange on said reflector, means carried by said body on which said reflector rests to prevent its inward movement, a lens ring provided with means adapted to rest on said flange, a hook structure projecting through said first named means, flange and into said. lense ring, and a spring secured to the inner end of said hook and bearing on the underside of said first named means but free of permanent attachment thereto for pulling said hook into holding engagement with said ring.

6. In a head light, a lamp body, a reflector therein, a laterally projecting flange on said reflector, a shelf structure carriedby said body on which sa d flange rests, a lens ring provided with an inner annular flat portion resting on said flange and having hook re ceiving slots therein, said flange being also cut away to accommodate the shank of said book, a wire bent to hook form projecting into said lens ring slot and adapted to engage the inner flat portion of said ring, and a. leaf spring carried centrally on the inner end of said wire and engaging the underside of said shelf structure but free of permanent attachment thereto for drawing said ring toward said reflector flange.

In testimony whereof I aflix my signature.
